In Southern California, generations of immigrants are creating an evolving definition of "American." Multi-American is your source for news, conversation and insight on this emerging regional and national identity.

The report, which provides a snapshot of the current undocumented population in this country, finds that 91 percent of the undocumented parents who had babies in the United States over a one-year period ending last March had already been here several years.

Some of the details:

The Pew Hispanic Center analysis also examined year-of-arrival patterns for unauthorized immigrant parents of babies born from March 2009 to March 2010, to see how long the parents had been in the United States before their children were born. If year of arrival was available for both parents, the analysis used the most recently arrived parent.

According to the analysis, 9% of these unauthorized immigrants who had babies in 2009-2010 had arrived in the U.S. in 2008 or later. An additional 30% arrived from 2004 to 2007, and the remaining 61% arrived in the United States before 2004.

Social media has played a remarkable role not only in how Egyptians used it to coordinate the anti-government protests that are now in their ninth day, but in how the world has witnessed, relayed information, and organized around the crisis.

Among Egyptian Americans, Facebook has played a big role in communicating, commiserating and organizing around the protests, as many have done in recent days to stage solidarity rallies in Los Angeles and other U.S. cities. Many of the Facebook pages dedicated to the Egypt crisis are administered out of the United States (where they tend to be pro-demonstrator).
